THIN FILM TRANSISTOR ARRAY SUBSTRATE, THE METHOD OF THE SAME

摘要

Disclosed is a thin film transistor array substrate, comprising: a substrate; a gate wire formed on the substrate; a wiring insulation layer formed on the gate wire; and a source wire or a data wire, formed on the wiring insulation layer, wherein a semiconductor pattern is formed on a lower portion of the gate wire in an area in which the gate wire is overlapped with the source wire or the data wire. According to the present invention, a problem on step coverage can be resolved.
